Shogi professional

Tosa's only tournament victory as a shogi professional came in 1998 when he defeated Toshiyuki Moriuchi to win the 32nd Hayazashi Shogi Senshuken.[2]

In August 2010, Tosa defeated Kiyozumi Kiriyama in 69th Meijin Class B2 league play to become the 42nd professional to win 600 official games.[3][4]

In March 2017, Tosa finished the finished 75th Meijin Class C2 league play (April 2016 – March 2017) with a record of no wins and 10 losses, earning a second demotion point which meant he was only one point away from automatic demotion to "Free Class" play.[5] As a result, he declared his intention to the Japan Shogi Association to become a Free Class player as of April 2017 rather than risk automatic demotion.[6]

On June 8, 2020, the Japan Shogi Association announced on its website that Tosa had retired from professional shogi. His official retirement date was given as May 14, 2020.[7]
